Chelsea Kane, Mark Ballas, Pia Toscano perform Rebecca Black's 'Friday'

Is Rebecca Black's "Friday" not, like, totally over yet? Apparently not for this season's "Dancing with the Stars" hopefuls. Chelsea Kane, Mark Ballas, Romeo, Chelsea Hightower and --surprise! -- Pia Toscano had some fun fun fun fun behind-the-scenes singing, rapping and beatboxing a version of the viral video hit.

Chelsea mainly holds the whole production together, though Mark Ballas -- we have to admit -- has a pretty mean beatbox going. Romeo freestyles some rap while Chelsea Hightower and fallen "Idol" Pia Toscano mainly dance around looking slightly embarrassed. We understand.

Even more embarrassing? Chelsea appears to have put some practice time into her rendition.

Come on, watch it. We know you "so excited":
